  "abstract": "We demonstrate for various systems that the variance of a wave packet $M(t)\\propto t^\\nu$, can show a {\\it superballistic} increase with $2<\\nu\\le3$, for parametrically large time intervals. A model is constructed which explains this phenomenon and its predictions are verified numerically for various disordered and quasi-periodic systems.",
